Abstract
Methods and systems for gravity-based energy storage may utilize various controls. For example, a control system for a gravity well may include an active front end controller (AFE) configured to receive a plurality of reference signals and a plurality of target control parameters. The system may include a rate limiter coupled to the AFE controller and configured to adjust a rate of change associated with each of the plurality of target control parameters based, at least in part, on the plurality of reference signals. The system may include a speed control loop coupled to the AFE controller and configured to communicate with a variable-frequency drive (VFD), the VFD configured to store the plurality of target control parameters. The system may include an AFE component coupled to the AFE controller and configured to communicate with a grid based on the plurality of target control parameters.
